I never meshed with my Powerball V1. For me it had a hollow mid sound that I couldn't dial out. I just wasn't happy with it. Yeah, the cleans are good but no better than a Herbert, Cobra, and more.
For me the Powerball sounded like a crappy version of a Diezel Herbert. Both Diezel and ENGL share that "clean" hi gain tone that is all crunch and no fuzz and grit like a Recto or Uber, which is really cool, but it just didn't work the best for me when compared to the Herbert. I did however never have a chance to try a clean boost with it, that might help with the hollow mids problem with that amp.
